l' .n/IPRQVMENT IN Dumme-APPARATUS.

Be it known that I, JOHN Roy, of New Orleans, in the parish of Orleans,.and State of Louisiana, have Y invented a new and improvedDraining-Apparatus;

and Ido hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same,

. reference'being had to the 'accompanying drawings,

forming part of this specication, in whie Figure 1 is a verticallongitudinal section of my im-V proved `drainingapparatus, `takenthrough the line a: x,

Figure 2 is a top view of the same, partly in section, through the liney y, lig. 1; f Similar letters of reference indicate like parts.,

My invention has for its object to furnish an improvedapparatusfor'draining low, overiiowed, or

swamp lands, which shall be je'iective and reliable in operation, and soconstructed that it may be placed` under the water of the canal,and mayforce the water out through the levee or dike whileworking only againstthe head ofwater outside.

And it consists in the construction and combination of the various partsof the apparatus, as hereinafter A are the steam-cylinders by which thepumpsare worked, one or more of which may be used,.a11d which maybeplaced Yin a `water-tight compartment, B, of the apparatus, so as tobe at the same level as the pumps to be worked, as shown in iig. 1;orthe said'cylinder or cylinders may be plaoedat a higher level, and`connected withl the piston-rods of said pumps by suitableconnecting-rods and levers.`

C C are compartments communicating with the canal Vinto which the waterowsfrom the land to bediaiued,

by means of openingsc', formed, in the walls of saidV compartments.

The openings c are provided with sliding or other gates D, by means ofwhich the entrance of the water,V

into 'the compartments C may be prevented when de- The openln gs c`shouldals'o be provided with screens or gratings E, to prevent theentrance, into the compartments O, of substances that would choke thepumps or interferewith their proper working. g

Fare the piston-chambers of the pumps, which are y made long, broad, andshallow, as shown in gs. l and VZ, so that they `may be worked, whenrequired, under a low inside head of water.

tached to the end of the piston-rod H.

' The otherY part, g, is perforated, or has its middle part cut away,and is connected with the part gl by and pass through holes in the partg, so that the said part, g2, may have a play of -about six-inches.

forward, they are perfectly tight, and push the water out through thedischarge-openings f of the piston, or pump-chambers F, and when thepistons are drawn back, the o part g2 falls behind the part '.q, andallows the water to ow freely into the chambers F;

of the outside head lof water, and are opened by the outward pressure ofthe water as it is forced out byv the pistons G. l l

By this construction of theapparatus, it may be placed at any desireddepth below the water in the canal, vin to which ows the water from theland to out, against theV outside head of water, whollyuniniiuenced bythe'inside head of water..
